Remember, if you increased tread width you have to decrease side-wall height.
For example OEM tire is 215/70/16 go to next size rim 17" tire size is, 225/65/17, 235/60/17, this will affect loading and handling.
Do not increase two sizes and kept height ratio the same, remember if you increase tread width you must decrease side-wall height. To keep speedometer and transmission happy.
As you increase tire size and decrease side-wall, you will lose the benefit of side-wall abilities to obsorb shocks. You'll feel imperfections in the road, but the trade off is great handling improve dramatically.
